WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 341,692, dated May 11, 1886.

Application filed November 2, 1885. Serial No. 181,661.

To aZZ whom it may concern.-

Be it known that I, JOHN ROBINSON, a citizen of the United States, residing at Bryan, in the county of XVilliams and State of Ohio, have invented certain new and useful Improvements in WVashing-lllachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to made and use the same.

My invention relates to washingmachines, and has for its object to simplify and cheapen the construction of the several parts and toincrease their efficiency; and it consists in the construction and the combination of parts, hereinafter particularly described, and then specified in the claims, reference being had to the accompanying drawings, in which- Figure l is a vertical longitudinal section through the machine. Fig. 2 is a plan View; Fig. 3, a vertical cross-section; Fig. 4, a perspective of the removable bottom rubber, parts of it being broken away. Fig. 5 is asection through a part of the tub, showing the manner of forming the double seam where the bottom and sidesjoin.

In the drawings, the letter A designates the standards or legs,connected together by longitudinal bars B and crossrods C, which pass through said bars and legs, and may have nuts D on their ends. To the upper portion of the standards are secured the longitudinal bars or side pieces, E, from one to the other ofwhich extends the cross end pieces or bars, F, one of which is smooth on its inner face and the other corrugated, as shown, the latterto form a rubbing-surface when it is desired to rub by hand. The two side pieces, E, are connected together at opposite ends by rounds G, which serve as handles by which to lift the machine.

The main portion of the tub-sides and hotto n1-is composed of metal, the sides Hbeing secured to the bottom I, which also constitutes the ends, by a double seam or joint made by bending the side edges, to, of the bottom downwardly and inwardly to form a hook,and then bending the lower edges of the sides inwardly,

then upwardly, and then outwardly toward the sides, as shown, so as to form a hook, I), interlocking with the hooks a, thereby forming a close and strong double joint that will also brace and stiffen the metal body, and

(No model.)

at both ends and secured by fastening-pins (Z to the cross-pieces F.

In the bottom of the tub there fits a removable rubber, J, composed of a series of bars, K, formed centrally with a V-shaped groove, and having its upper edges beveled to form a 6 double-ribbed rubbingsurface to each bar, as shown. These bars are held together at distances apart by flexible rods orstraps L, passing through holes in the bars, so that there will be a rod on each side of the bottom rubber. These rods project from one of the end bars, as shown, so as to form pins, which enter openings or perforations in one of the end pieces, F, and thus assist in holding the rubberin place. The connecting rods or straps being elastic,and the rubber being of a different contour from the bottom of the tub, when the rubber is pressed into place its tendency to expand or resume its normal shape causes it to bear with an elastic pressure against the lower edges of the end pieces, F, so that it will thereby be securely held in place. For the purpose ofits easy removal, a finger strap or loop, M, may be secured to it at one end, so that bypulliugthereon the rubber may be contracted and then 8 lifted from its place.

There is suspended within the tub an oscillating rubber composed of side pieces,l\ ,semicircular in form and connected together by a series of bars, 0, grooved similarly to bars K, which. form a semicircular rubbing-surface. From the side pieces there extend upwardly the bars P, which are braced by the cross-bars Q. The upper one of the bars Q is journaled in the straps R, the opposite ends of which are journaled or pivoted to the standards A--the one by a pin, a, projecting from one standard, and the other by a removable pin, f, passing through the opposite standard and into the eye of the strap. The straps thus serve to hinge the rubber to the machine, and the withdrawal of the pinf permits the removal of the oscillating rubber. The rubber is oscillated by means of a lever, S, secured to the bars Q, and

a lever, '1, extending diagonally from crosspiece U to the side of the tub serves as a means to exert the desired pressure on the clothes and also to lift the rubber from the tub. By extending the lever T as described it is brought to the side of the tub, where it is most convenient to be grasped by the left hand, while the right is used to oscillate the rubber.

A bar, V, for the attachment of a wringer, extends from one standard to the other on one side of the machine, and a metal plate, XV, extends from the bar V to the inside of the side E, so as to direct water from the wringer to the tub. A bar, Y, extended across the tub at the end where the smooth-faced cross-bar is, prevents the Water from splashing over that end, and the corrugations in the bar F of the opposite end prevents splashing at that end.

The operation is apparent from the foregoing description of the several parts; and

Having set forth the merits of my invention, what I claim is- 1. The combination, with the tub, of the straps pivoted thereto by pins, one of which is removable, and the oscillating rubber journaled in the opposite ends of the straps, substantially as described.

2. The combination, with the tub, of the straps hinged thereto, the rubber journaled in the straps and provided with alever to operate it, the cross-bar connecting the straps,and the lever extending from said cross-bar obliquely across the tub, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN ROBINSON.
